D4 Trombone Position
How to play D4 on the trombone: 1st position. — on the 5th partial, in bass clef, sounding exactly as written.
The diagram shows the trombone from the side with the slide pointing down: the dark bar is the slide brace, and it stops at the numbered marker for this note's position — the slide is all the way in, resting gently against the stops. The staff is in bass clef, the trombone's home clef, and in bass clef the trombone sounds exactly as written.
Hear D4 and try the position
Pick an instrument and a note and the diagram updates instantly — filled keys are the ones you press. The same finder sits on every note page, pre-set to that note.
The D4 position, step by step
- Move the slide out to 1st position — the slide is all the way in, resting gently against the stops.
- First position is the home position: every harmonic of the open tube is available here, and your lips and air choose which one sounds.
- Check the pitch against the harmonic: if the note will not speak cleanly, the slide is usually close and the lips are aiming at the wrong partial — re-centre the buzz before moving the slide further.
In short: 1st position.
Alternate position for D4
4th position.
Yamaha’s official chart badges this alternate, and it solves a real problem: D4 in 1st position rides the flat 5th partial and the slide cannot come in to correct it, but D4 in 4th — on the F4 harmonic — tunes cleanly. Many teachers teach this as the default D4 for sustained notes.
About D4 on the trombone
The middle register is the trombone’s home territory — the 4th, 5th and 6th partials, where school band music mostly lives. This is where the classic alternate positions appear (F3 in 6th belongs to the register below, but B♭3 in 5th and D4 in 4th are here), and where the flat 5th partial has to be managed: its notes sit about 14 cents low and want the slide a touch in from the landmark.
D4 is the 5th partial, and the 5th partial is flat — about 14 cents flat, by the physics of the harmonic series. In 1st position the slide cannot come in to fix it, so players lip it up, or use the alternate: D4 in 4th position on the F4 harmonic, the version Yamaha’s chart badges and many teachers recommend outright. Every other 5th-partial note (D♭4, C4, B3) can be helped by bringing the slide in slightly; D4 alone cannot.
D4 is note 17 of the 32 in the full trombone slide position chart, sitting between D♭4 below it and E♭4 above it. Like every position on this site, it was checked against Yamaha’s official chart and the NoteAtlas slide position chart before publishing.
Practising D4
Practise this note against a tuner, and if it belongs to the 5th partial (B3 to D4), expect to sit a little inside the textbook landmark. Then play it in a phrase — position is a habit of the arm, not a measurement.
Questions about D4
What position is D4 on trombone?
1st position. D4 is played on the 5th partial (harmonic) of the trombone's tube in the middle register. The full step-by-step is on this page, and you can hear the note with the Fingering Finder.
Does D4 sound as written on trombone?
Yes. In bass clef the trombone is a non-transposing instrument, so written D4 sounds as concert D4 — the same pitch a piano plays. Only brass-band treble-clef parts transpose.
Is there an alternate position for D4?
Yes — 4th position. Yamaha’s official chart badges this alternate, and it solves a real problem: D4 in 1st position rides the flat 5th partial and the slide cannot come in to correct it, but D4 in 4th — on the F4 harmonic — tunes cleanly. Many teachers teach this as the default D4 for sustained notes.
